Messi missed a penalty and hit the post as Barca pressed in the second half, but Rosell does not blame the diminutive attacker for their exit.
“I do not think Barca has been knocked out by Messi’s penalty,” he said. “After 180 minutes we had many occasions and they took three of theirs. That’s what happened.
“The way we play is taught in la Masia and is not going to change. Football is a game. Sometimes you win and sometimes not. We win and lose.
“I think every time we’ve had a setback against this season it has been unfair, but opposing teams play well against us and we must accept it.
“Despite failing to qualify for the final and having had a bad week, the fans have been supporting us.
“I am very proud of them. I’m not happy with the result but I am proud.”
